' z claims. (C1. lei- 12) This invention relates to smoking pipes, andits general object is to provide a pipe that includes a trap which notonly diverts the smoke to cool the same, as well as blocks, collects andprevents the passage of particles of tobacco, other matter andunpleasant products of combustionand the like from the bowl of the. pipeto the mouth piece but condenses and collectsthe moisture in the smoke,with the result the latter is cooled, cleaned l1() and dried before itreaches the mouthpiece.

A further object is to provide a pipe that includes a trap which iscapable of performing all of the above functions, yet will not interferewith free drawing or passage of the smoke, and can be easily installedin any pipe now in general use, without materially changing thestructure of the pipe or the appearance thereof, in that the `trap ispractically concealed from view. v

Another object is to provide a` pipe that includes a trap of thecharacter set forth,.which is simple in construction, inexpensive tomanufacture, can be easily applied and removed with respect to the pipe,will not interfere with cleaning of the pipe in the usual manner by theso-called ,25 pipe cleaners and the like, and is extremely efflcient inuse and service.

This invention also consists `in certain other features of constructionand in the combination and arrangement of theseveral parts, to. behereinafter fully described,.illustrated in the accompanying drawing andspecifically ypointed out in the appended claims.

In describing the invention in detail, reference will be had to theaccompanying drawing wherein like characters denote like orcorresponding parts throughout the several views, and in which:

Figure 1 is a side elevation of a pipe constructed in accordance withthe present invention, with a part of the stem and bowl broken away toillustrate the application of the trap thereto.

Figure 2 is a sectional view taken on line 2 2 of Figure 1.

Figure 3 is a sectional View taken approximately on line 3 3 of Figure1.

Figure 4 is a sectional View taken through the trap in applied positionand shows by arrows the course ltaken by the smoke, in passing about thetrap and through the same.

Figure 5 is a sectional View illustrating the only change that isnecessary in the pipe strueture to apply my trap thereto.

Figure 6 is a sectional view taken approximately on line 6-6 of Figure4.

55 Figure '7 is a top plan view of the trap per se.

Figure 8 is a perspective view of the partition or baille plate of thetrap.

Referring to the drawing in detail, the reference numeral I indicatesthe bowl of the form of pipe shown, 2 the stem and 3 the mouth piece,the latter being frictionally mounted in the stem and having a groovedinsert member Il frictionally secured in the inner end thereof.

Allof the foregoing structure is 'well known and is shown and describedin orderto disclose the present invention, which in fact is .a trapcapable of being associated with any type of smoking or tobacco pipe,and for that purpose, the stem is provided with a bore 5 which extendsfrom the bottom of the stem, through the smoke vpassage 6 thereof, andabove the passage to provide what may be termed a smoke chamber 1, asbest shown in Figure 5 of the drawing. The bore 5 may be disposed at anyplace along the length of the stem, but is preferably disposed adjacentto the juncture of the stem with the bowl I, as A shown in Figure 1.

The trap includes a hollow cylindrical body 8 of a size to lit withinthe bore, and the body may be frictionally mounted or threadedly securedtherein. In any event, the body is of a height to extend into the smokechamber I so as to bridge and close the smoke passage 6, and has an openupper end and a closed lower end or bottom S, the latter beingpreferably integral with the vertical wall of the body and formedthereon to provide a flange Ill engageable with the lower surface of thestem to not only limit the application of the trap within the bore 5,but to provide means to receive a knife` or finger nail of the user tofacilitate the removal of the trap from the bore.

The wall of the cylindrical body is cut away as at II, fromdiametrically opposite points at the upper end thereof, to a point thatis preferably below the transverse center of the body, to provide arecess in the wall which when the trap is in applied position, faces thebowl, as best shown in Figure 1. The portion of the wall opposed to therecess or cut away portion I I is provided with a substantially crescentshape slot I2, and the lower end of the slot as Well as the lower end 0fthe recess is preferably ush with the lower portion of the smoke passage6, as best shown in Figure 4.

It will be obvious that the hollow cylindrical body with its bottom 9and open upper end provides what may be termed a container that issubstantially cup-shaped, and disposed vertically therein across thediameter thereof is a partition fill I3 which divides the container intochambers I4 and I5. The partition is co-extensive with the height of thebody 8 and frictionally ts therein for vertical movement and formed onthe upper end of the partition is a flange I6 to facilitate the movementthereof, it being apparent that the flange acts as a finger piece, andby that construction it will be Vseen thatthe partition can be readilyremoved from the container and adiusted therein, and the adjustablefeature thereof makes it possible to control the flow of the smoke andthe draft to a certain extent. However, the partition may be xed, but ispreferably adjustable. When the partition is raised above the bottom 9of the container, a passage will be providedV between the bottom and thelower edge of the partition to allow smoke to pass therethrough,especially when the container is empty, but when solid matter and liquidaccumulate therein, such lwill close or partially close that passage,consequently all or the maximum amount of smoke must pass through thechamber 'I. In any event, the partition directs smoke through the smokechamber, which acts to cool the same, and when the smoke contacts thepartition or baille plate, it will be obvious that the moisture thereinis condensed and collects within the chamber I4, which also acts toreceive all solid matter and the like from the bowl and prevents thesame from passing kto the mouth piece. The chamber I5 likewise receivesliquid produced by condensation and saliva which may pass through themouth piece, consequently it will be seen that the smoke is cooled,cleaned and dried before it reaches the mouth of the user.

It might be mentioned, that while the upper wall of the smoke chambery Iis shown as being concaved and the bottom 9 of the trap is flat, theformer may be convexed and the latter concaved. In the event the bottom9 is concaved, or the inner surface thereof is formed in concavedformation, the lower edge of the partition I3 is curved to follow theshape thereof, and the partition which is shown as being straight may becorrugated, and the corrugations preferably extend transversely thereof.

It is thought from the foregoing description that the advantages andnovel features of the invention will be readily apparent,

It is to be understood that changes may be made in the construction andin the combination and arrangement of the several parts, provided thatsuch changes fall within the scope of the appended claims.

What I claim is:

l. A smoking pipe comprising a bowl, a stem and a mouth piece, said stemhaving a bore therein extending through the bottom and the smoke passagethereof to provide a smoke chamber in the wall above the passage, acontainer detachably mounted in the bore and having an open top disposedwithin the chamber, said container having a flanged lower end to limitthe movement thereof in the bore and to facilitate its removaltherefrom, a removable partition providing a baille disposed verticallywithin the container across the diameter thereof for frictionalengagement therewith, means on the upper end of the partition tofacilitate the removal thereof, said partition being co-extensive withthe height of the container and dividing the latter into chambers, oneof said chambers having an open wall portion directed toward the bowland the lower edge of the open portion being flush with the lower edgeof the smoke passage, the other chamber having an opening in its walldirected toward the mouth piece and disposed a considerable distanceabove the bottom of its chamber, and said opening being substantiallycrescent shape with its curved edge lowermost and disposed flush withthe bottom of the smoke passage.

2. A smoking pipe comprising a bowl, a stem and a mouth piece, said stemhaving a bore therein extending through the bottom and the smoke passagethereof to provide a smoke chamber in the wall above the passage, acontainer detachably mounted in the bore and having an open top disposedwithin the chamber, said container having a flanged lower end to limitthe movement thereof in the bore and to facilitate its removaltherefrom, a removable partition providing a baille disposed verticallywithin the container across the diameter thereof for frictionalengagement therewith, said partition being co-extensive with the heightof the container and equally dividing the latter into chambers, one ofsaid chambers having an open Wall portion directed toward the bowl, theother chamber having an opening in its wall directed toward the mouthpiece, said partition being adjustable and movable vertically for thatpurpose into and out of the smoke chamber to vary the flow of the smoketherethrough, and a flange on the upper end of the partition andproviding a finger piece to facilitate the removal and adjustmentthereof.
